Description

[Detailed Description of the Invention] The present invention provides a method for automatically mounting circuit components on a circuit board.
Regarding the circuit component holding band for automatic mounting used to facilitate the supply of circuit components for mounting.Nowadays, the mounting of components on circuit boards is rapidly moving towards automation, and the position of the circuit components to be fixed to the holding band is important. Requirements for accuracy and adhesion strength are becoming increasingly strict. On the other hand, the conventional holding band 11 is simply a long and narrow band-like member, as shown in FIG. It is.

FIG. 2(a) is a perspective view showing a state in which the transistor 3 is fixed to the holding band 11 of FIG.
03 terminals 3 a, 3 b + 3 C are ・Retaining band 1
It is fixed to one side of 1 with adhesive tape 4.

However, in such a fixing method, as shown in the partially enlarged view of FIG. 2(b), the terminals 3a and 3b of the transistor 3
, 3C and the adhesive tube 4. Therefore, in the same figure (for the lateral force F of at, the transistor 3
The disadvantage is that displacement and deformation are likely to occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a circuit component holding band for automatic mounting in which circuit components for mounting can be firmly fixed and held with good positional accuracy without causing the above-mentioned positional displacement.

The automatic mounting circuit component holding band of the present invention has a long and narrow strip shape and fixes and holds the terminals of a large number of automatic mounting circuit components along its length, and It has a structure in which a groove into which the terminal is inserted is provided parallel to the surface of the band at a position where the terminal is fixed.

Next, the present invention will be explained using actual precedents.

FIG. 3 is a perspective view of one embodiment of the present invention. In FIG. 3, on one side of the holding band 1, grooves 6a16b16C into which the terminals of the transistors to be held are inserted are provided at regular intervals parallel to the surface of the band.

FIG. 4(a) is a perspective view showing a state in which the transistor is fixedly held by the holding band shown in FIG. They are respectively inserted and fixed with adhesive tape 4. FIG. 4(b) is an enlarged perspective view of the terminal bracket shown in FIG. 4(a), and the three terminals 3a, 3b, 3c of the transistor 3 are in the matching grooves Cy', Gb.

6C and its movement is restricted by the wall surface of the matching groove, so the fixing position is accurate and it is firmly fixed without fear of displacement.

FIG. 5 is a partial perspective view of another embodiment of the present invention, and FIG.
In the figure, a groove 6 a into which the terminal of the circuit component to be held is inserted.
A taper t is attached to the entrance of '+6b'+6c'. This tapering makes it extremely easy to insert a terminal into this groove. However, even if the edges of the groove are rounded, it is also easy to insert a transistor terminal into the groove. In any of the embodiments shown in FIG. 4, if an adhesive is applied to the inner surface of the groove, the strength of fixing the transistor will be further increased. 4) It will be done.
